Understanding IEEE 802.11n Multi-Hop Communication in Wireless Networks
In this paper, the authors present a measurement study of the multi-hop behavior of the new IEEE 802.11n standard in an indoor mesh testbed. As main contribution, they quantitatively describe characteristics of IEEE 802.11n on multi-hop paths like throughput, aggregate size and utilized MIMO features. Furthermore, they show how to build an IEEE 802.11n indoor testbed capable of multi-hop communication. In an 8-hop chain topology, they observe that channel bonding nearly doubles the throughput for any fixed path length. The mean aggregate size in number of frames at each node is also doubled by channel bonding.
